lApplication filed April 9, 1925. Serial No. 21,760.

This invention relates, generally stated, to door fasteners and has more especial relation to latch mechanism for refrigerator doors, cold stora room doors and the like.

The leading oect of the present invention is to provide a door fastener of the character stated in which is combined simplicity and eliiciency of structure, simplicity in manipulation, quick and positive locking operation and cheapness of manufacture. Other objects reside in the provision of general details of construction and arran ement and combination of parts for attaining theresults sought by said leasing object.

. Other and further objects not at this time more particularly pointed out will be hereinafter referred to.

The invention consists of. the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the 'accompanying drawings forming part hereof, and in which:-

Fig. 1 is a view in front elevation, of latch mechanism embodying the invention.

Fig. 2 is a view in section taken upon the line 2-2 of Fig. 1.

Fig. 3 is a view in end elevation of the keeper parts shown in Figs. 1 and 2.

Fig. 4 is a view in section taken upon the line 4-4 of Fig. 1.

Fi 5 is a view in elevation of the keeper detac ed, and

Fig. 6 is a fragmentary view illustrating details of construction of the end of the latch operating lever shown in Fig. 2.

For the 4purpose of illustrating my invention I have shown in the accompanying drawings several forms thereof which are at Eesent preferred by me. since the same have en found in practice to give satisfactory and 'reliable results, although it is to be understood that the variousy lnstrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

In the drawings, the reference numeral 1, designates a door-jamb and reference numeral 2 `designates a door hinged withI respect hereto. A description will be `given first of the keeper parts as carried by the vis said detent 20, the

door-jamb and thereafter a description of the latching elements as carried by the door will be given.

as by the screws 3 is a casting 4, best seen' in Figs. 1, 2 and 3. This casting has a lon- Uitudinal bore 5 fitted within which is a keeper 6V the rear of which is apertured as at 7, fitted within which is a coiled spring 8 abutting against the rear wall ofcasting 4 and normally pressing said keeper 6 toward the right in Figs. l and 2. 'The nose of the keeper is flat as at 9 and the opposite faces are inclined as at 10 and 11. The nose of the keeper `is also provided With shoulders 12 and 13 which are arranged to abut against a plate 14, screwed as at 15, see Fig. 3, to the front of casting 4 to limit the forward movement of said keeper..

`Taking up now the latching mechanism as carried by door 2 and which cooperates with the keeper just described, reference numeral 16 designates an elongated late secured to the door 2 as by screws 1 This platey is substantially T-shaped, as seen in Fig. 1; is erforated at one end as at 18; and carrie at its other end a fixed detent 19 in the form of a plate of hardened metal. Having hin ed relation with the plate 16 is a movable detent 20. Such detent is best seen in Fi 4. The plate 16 is provided Iwith lugs 21, plvotally carried by Vwhich is a. rod 22, fixed upon which by means of a pin 23 bevelled nose 24' of which is aligned with detent 19, see 2. A coiled spring 25 is interposed between plate 16 and the nose end of detent 20 to normally maintain the stop 26 of the opposite end of said .detent 20 in abutting relation with plate 16, see Fig. 2. The stop 26 and the adjacent part of the detent form a hand grip portion 27 so that to open the door the operator grasps part 27 and pulls outwardly thus moving the bevelled end 24 of the detent inwardly to ride over and push inwardly keeper 11. As keeper 11 moves to the left in Fig. 2,`and as the operator still pulls upon door 2, the fixed detent 19 rides` outwardly over the receding end of the keeper and thus frees the door for ready opening. It is thus seenl that normally the keeper is between both fixed and movable dctents, and abuts against the fixed detent, there being however clearance between the movable detent and said keeper as clearly seen in Fig. 2. Obviously to close the door 1, the fixed detent first moves the keeper in- Fixed to the door-jamb 1,

.11. The end 30 of wardly to (permit the fixed detent to pass beyond sai keeper. When the door 1 1s 1n locked position as seen in Fig. 2, the 'said door may be opened from within a refrigerating room or the like by pushing u on knob 26 of rod 29 and thus moving en of said rod 29 against the end 28 of detent 27 the detent is moved about 'its pivotal point 22 to push inwardlythe sprlng pressed plunger 11 and thus permit detent 19 to pass outwardly beyond the spring pressed keeper rod 29 is provided with a hardened steel ball 31 which rests w1th1n the concaved part 32 of the end 28 of detent 27 and forms a good bearing and thus doing away with pivotal or other connections. pin 33 is employed to limit the rearward movement of rod 29.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enu merated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it'is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
